Specitleation of Letters -Iateiit Patented Jan. 24,.-1911.

Application filed January 24. 1902. Serial No. 91.120.

To all whom it may concern.:

Be it'known that LVILLIAM B. FLEMING n u .c n c a citizen of the United States, residing at Los Angeles, in the county of Los Angeles,

State of California, have invented new and useful Improvements iii Electrically-Operated 0r'gaiis ot which the following is a specification.

My invention has for its objects'certain new and useful improvement-s in electrically actuated pipe organs; and it consists of the combination, arrangement', and structure 0f certain devices l. rt nafter described and claimed,l and illustrated in 'the accompanying drawings, In whichligure 1 is a diagrammatic View, partly in section, illustrating part-s of my inven-l the regulating screw for regulating the tention. Fig. 9 is'a vertical section of the pallet box and pouch pneumatic. Fig. 3 is a View `in diagraniaiid in section, and partly in elevation. illustrating features of my in vention. Fig. 4 is a diagrammatic View, partly in section, showing certain features of my invention. Fig. La shows a plurality of stops 80. Figs. 5 and Gare detail views of the draw stop, .shown in' Fig. 4. F igs. T and 8 are plan views ot' parts shown iii Fig. 2. Fig. 9 is agdetail. View of parts shown in Fig. 2. Fig. 10-is an enlarged longitudinal central section of the pouch pneumatic and sion ot' the pallet spring shown in Fig. 4. iFig. 1l is a side elevation ofa part of the crescendo mechanism shown iii Fig. 4. Fig. 1Q is au end View ot', the parts shown in Fig. l1.

Iii the diagraniinatic drawing, represented iii Fig. 1, the great chest is represented by the numeral 1, the swell chest by 2, the choir chest by 3,. the pedal chest by 4, thegr'eat keys by 5, the swell keys by G, the choir keys by 7, and the pedal keys by 8. The various circuits are the same as. those. shown in the patent issued to nuon February '2Uth,'iio0, l

supplied with air from the. bellows (not Shown) during the time the organ is operated. The chestfv operates the great. organ. Coupler contact' il, allixed to pneumatic l0, is brought into or disconnected from contact with springs 1l and l2 by the action of pneumatic 10. 'lhis coupler contact is so arranged that it. pi'm-l'sfor the shrinking makes-a perfect contact, or is perfectly freed from contact, which is not the case in all contacts for a like purpose with which I am acquainted. lVhen. the Great key 5 is de- U0 pressed bythe finger of t ie operator t'lie circuit is closed and electro-magnet 13 is eiiei'- gized, thereby attracting and drawing to 1t its armature 14, which closes the opening hetween channel 15 and wind box 1G and opens -65 vcommunication between channel 15 and channel 17, thereby permitting pneumatic 1S to exhaust to the open air. To the bottoni of pneumatic 18 is rigidly affixed arm lll, to

which is connected rod 20, to which are attached pallets 21 and Q2. Rod '20 is held normally depressed by spring Q3. ll'heii pneumatic 18 is exhausted, rod 2O is raised against the pressure of spring and carries pallet 21,to close port 2st, thereby clos- 75 jing communicationbetween wind box 1 and channel 25, and at thtl saine time it carries pallet QQ away from port QG. so tliat'chaiinel 25 is in communication with the outside air. channel QS and pipe 29, which connects chaunel :'28 with channel 9.5. which brings coupler Contact 9 in contact with springs 11 and 12, as shown in Fig. 7. These springs are elec- Pneiiinatic 10 then exlnuists through 80 trically connected one with the swell and the other with the choir organs when the proper stops, or switches, are drawn. This conipletes the circuit through the coupler 'or switch, as described iii Patient #648,840, is-

sued to me on- Feb. 20th, 1900, and, when 90 this coupler switch drawn, enables the operation ot' swell and choir organs :it the saine time, from the great organ keys, as described in said patent, theiinprovement breaking tlieciictiit through the coupler contact f) and connected mechanism. At the same time pneumatic 10 exhausts, pneumatic 30 exhausts through channel 25, and by vherein being iii the 'manner of making and 95 means of rod 3l, carrying pallets and 33, 100

closes port 34, which forms communication between pallet box 1 and. channel 35, and opens poi-t 3G, thereby pei'iiiittiiig pouch pneumatic 37 to exhaust through channel lVheii the pouch pneumatic 3T is exhausted 10? it operates pallet 3S to open communication between wind chamber 3f) and channel 40, thereby permitting the air from kbox 3i) to pass into and through channel 40 and operate organ pipe 41. lVind box lt is in coininunication with wind box 1 through bleed and swelling of the wood, and at all times l hole 27,shown in dotted lines in Figs. 2 and 9.

causes pneumatic 18 to become reintlated, causes pallet 22 to close port 26 and pallet 2l to open port24, and the several parts pei'- form the reverse operations to those described when the circuit was established, and

resume their normal osition, as shown in the drawings. Springp42, on the end ot' rod 31, assists in the reinfla tion of pneumatic 30.

rlhe pouch pneumatic and its operation ai'e fully` described in Patent #593,391 issued tome Nov. 30th, 1897, but in that patent there is nothing provided to regulate the tension of the spring 37 which closes the pallet which controls the port between the wind chest 39 and thechannel which leads to the organ pipe.l Intliis device I regulatethe tension of the spring by means of screw 43 which passes through the casing of the ouch and bears upon the spring interme iate the ends to make it greater or less as the wind pressure is higher or lower, the same varyinvi from 3% inches to 20 inches so as to malte the action 'ofthe pallet perfect. Vithout this regulating screw it is very diicult to produce a spring which will give the pallet a perfect action. The stud 46, passing through the slot 48 in arm 47, attached to the to of pneumatic 10,A limits the movement oitlie top boa-rd ot' the pneumatic to the distance between the nuts 44 and 45, on said stud 46, so as to regulate and make certain the clearance and contact of contact 9 with sprin s 1 1 and 12. Spring 49', shown in dotte lines on the side of pneumatic 10, in Fig. Q, and in full lines in" Fig. 7, opens it after its collapsing force is withdrawn. W'hen playing the great. organ, pneumatic 10 will operate every time :i key is depressed, thereby closing the circuit and causing contact 9 and springs 1 1 and l2 to come together, thus keeping the contact clean.

il' It will' be understood that the operative mechanism of the swell and choir chest are the same, that is, one is the duplicate ot the other, and that by coupling the swell chest to the great chest, and. the choir chest to the great chest, the pipes -operated by each chest are played by the operator ofthe great keys at the same time that the great organ' is operated.

By coupling the great chest to the pedal'.

keys, and the swell chest tothe pedal keys, the pipes operated by cach chest, -and by the pedal chest are played by the operation of the pedal keys, thus giving as many lower Y notes of the manual as there are pedal keys.

-In other words, by couplinglswel to great,

and choir to great, and by drawing great to pedal coupler, all the lower notes of the manuals are produced by the operation of the pedal keys, in the same manner as though plied with wind from the organ bellows.

In the to of this box is pouch 50, from which lea s a. channel 51 in the top board of the box to the outer air. Normally the channelis keptclosed Aby the armature 52 of magnet 53, which keeps the pouch lled with air. To the bottom of thisv pouch is connected rod 54, on which is mounted pallet 56, which controls port 57, which connects the coupler box with channel 58, that lea-ds to pneumatic 59, which is held normally collapsed by spring 60. Channel 58 is a so in communication with the open air through port 61. Rod 54 also carries pallet 62, which is adapted to close portA 61, when the pouch is exhausted, as hereinafter explained. To the bottom board of pneumatic 59 is arm 63 to which is attaclied rod 64. The upper -end of this rod is attached to contact spring 65, which has a vertical movement in slot. 66, in supporting timber 67, to which timber is attached contact 68which is-electrically connected with the pedal pallet box. Qontact spring is electrically connected with the circuit which operates the organ. Magnet 5% is electrically connected with battery 69 in a circuit which norinalliy is open, and in which circuit 'is switch 70, which is controlled by pedal stop 71.

Now, when it is desired to connect great to pedal, stop 71 is drawn and the circuit which operates magnet- 53 is closed, thereby energizing the magnet which draws its armature out of passage 51so that pouch 50 may be exhausted. Theexhaustion of pouch`50 raises rod .54, which carries pallets 56 andGQ, to open communication between coupler wind box 49l and channel 58, and to close channel 5S to the air. The air .from the; coupler wind box intlates pneumatic 59, which causes rod 64 to depress spring (35 until it touches Contact 68, which establishes the circuit between pedal and great, and thereafter the' operation of the pedal keys will operate the lower notes of the great organ, at the same time that the notes of the pedal organ are'operated,`and by the same keys. The circuit runs from the great keyto the magnet 13, inthe great chest, thence through the common return d and r to battery 69. The wire b leads from the battery to all of the keys. When contact `65 enga es contact 68, as before explained, a

circuit will be established through magnet 'c of the pedal chest by wire d sothat whnthe greatl keys are operated the pedal chest, as

' organ may be, obtained by drawing the ar'm ot which is attached bar Tl. the other shown). where the chest pnc'uinatics are loi moved well as the `great chest is played. 'l`lc wirte leads from the battery wire to thc pedal chest and the wires f lead trom tbe pedal i chest to the switch mechanism. The 'various circuits connecting thc various organs together are shown tliagraininatically in l Fig. l. and the niechaninn t'or connecting the ditl'erent organs together. as before stated. is the duplicate ot' that above described. ln .similar manner. and by a'like n'ieclianisln. Ath'e choir chest. or organ. is separately connected with the pedal. and the choir chest. or organ. and the swell chest. or organ. are separately connected with the great chest. or organ. 4When the .several organs are connected with the great organ. all. the. notes ot' each of the connected organs are played at the saine time thatV the like notes of the great organ are played. and by the manipulation of the great organ keys.

In Figs. 1 and 4. 72 `the crescendo pedal, pivotally mounted on pi-yot 7?, to the lower end of which is connected to arni T5,.which arm is in turn rigidly aflixed to roller TG. of nonconducting material. vRoller 76 has a small tapering metallic plate TT, preferably of brass 'or copper, let in flush with the periphery thereof, which extends longitudinally and is electrically connected in the circuit that extends to the draw .stop wind-boxtnot cated. 'TS is a contact spring which is electrically connected to one side of battery 84 by line wire The other side of this battery is electrically connected to draw stop box of each organ. not shown. by line wire SV, TS are contact fprings Awhich are also electrically connected to the draw stopwind-` box ot' each organ. there being one of these contact springs for each draw stop., Contru-t` .sprint-f TS and TS normally rest on the nonc'oinlacking,portion of rolle!` Tt'. Tension www Tt) are provided to give to these sprines a proper contact with the ioller. By thc oscillation of pedal 72 the metallic strip TT on rollei-`76 brought into, or relroni. contact with the contact' si'nings which makes or breaks the circuit. As the metallic strip is tapering the contact and break thereof with thc contact spring is gradual. thereby producing a crescendo. It," will he obserred that. the crescendo of each proper stops.

ln Fig. l is diagrami'nati ally illustrated the connection between a portion of the ordinary stop mechanism and what I willl call the grand crescendo nicclianisni composed of thc roller and contact springs. S0 is thc knob of the .stop bar Sl to which is .secured contact bar 8'2. lVhen the stop drawn this contact bar is drawn into engagement-l with contacts S3 and. Sil. Contact S3 connected to one side of the stop mechanism I of one of the independent organs not shown, li) wire S5. Contact H3' is connected by wires ofi and H." withone side of battery 84. ll'ii'c 255 also connects contact TH with the battery. connected to the other side of the .stop mechanism ot the organ by wire 86, which wire also forms the return from the same organ of thtl `grand crescendo mechanism. The

contact springs TS are connected by wires Si' and ST' with the stop mechanism of the Iditt'erent organs.

Now. if some of the Astops are drawn. and others are not drawn, and the player wishes The other .side ot' the battery is 70 to produce a #forzando e'ect he obtains it 80' by the rotation otl roller TG, to bring all the` contact springs in Contact witl'i plate 7T; this operation in no manner interferes with those oi'gans in which the stops are drawn.

There are as many contact springs as there 85 are draw. stops 80 and couplers'to be used on crescendo on full organ, the whole numbei' varying with the size of the organ. and ranging from 4 to 150. The details of the stop mechanism are shown-in Figs. 4, .l

and G, and need notbe further described; the purpose of their illustration being to show connection between them operated by the foot and the usual stop mechanism.

The left hand portion of F ig. 4 is a plan 95 ,view of a part of magnets 13, removed from box 16, and Fig. 9 is a side view of one ofthe magnets. Fig. 8 is a plan of spring 23.

and connected parts, to illustrate its relation thereto. differentparts mentioned in the foregoing description, which are connected together to produce any ofv the ditfeient effects. are duplicated for each of the great'organ keys.
